            Status: REPORTED
          Severity: normal

  Target Milestone: ---

While cleaning my keyboard, I managed to somehow crash KHelpCenter (22.08.3;
this version isn't in the list).

I've narrowed it down to the following steps:
* Open KHelpCenter (e.g. by pressing F1 in KWrite).
* Press the following keys in sequence: F3, F1, F7
* Repeat the sequence: F3, F1, F7

Application: Help Center (khelpcenter), signal: Segmentation fault
